Which mechanism primarily causes uplift in fault-block mountain ranges resulting from normal faulting?

💡 Explanation

When a normal fault occurs, one block slides downward relative to the other, causing isostatic rebound because the removal of overlying material reduces lithospheric loading, initiating buoyant uplift. Therefore buoyant isostatic forces causes uplift, rather than compressional folding, differential erosion, or simple crustal thinning alone.
